South African Airways has advised its customers to contact its call centre or their travel agents to make alternate flight arrangements - or request a refund. This after the South African Cabin Crew Association and NUMSA announced that their members will embark on industrial action tomorrow morning over a wage dispute. SAA has cancelled all its domestic, regional and international flights scheduled for tomorrow and Saturday. All flights operated on SA Express, Mango, SA Airlink and other partners will not be affected.
